How much bigger is the Sum of first 50 even numbers than the sum of first 50 odd numbers?
Lunna [17]

Answer:

50

Step-by-step explanation:

Sum Even numbers

n = 50

d = 2

a1 = 2

The last number is

an = a1 + (n-1)d

an = 2 + (50 - 1)*2

an = 2 + 49 * 2

an = 2 + 98

an = 100

Sum of the even numbers

Sum = (a1 + a50)*n/ 2

Sum = (2 + 100)*50/2

sum = 102 * 25

sum = 2550

Sum of the first 50 odd numbers

a1 = 1

n = 50

d = 2

l = ?

Find l

l = a1 + (n - 1)*2

l = 1 + 49*2

l = 99

Sum

Sum = (1 + 99)*50/2

Sum = 2500

The difference and answer is 2550 - 2500  = 50

180-(120)
60

Evaluate using sine rule:
\frac{c}{sinC}=\frac{b}{sinB}

c=\frac{bsinC}{sinB}

=\frac{10sin90°}{sin30°}

=20
